Definitions
- This invention relates to tile making machines in which tiles are formed, normally by extrusion, on pallets.
- Pallets of deep section occupy more space than shallow pallets when vertically racked for transport into a curing chamber, requiring a larger curing volume for a given number of tiles. Pallets are required in large numbers in a tile production line and it is therefore desirable for reasons of expense to reduce the size of the pallets where possible.
- the invention provides a tile making machine in which tiles are formed on pallets conveyed in succession through the machine, including means for supporting the pallets, the support means providing a track level adjustable in height to accommodate pallets of different depth.
- pallets for tiles of different profile can be conveyed simply by changing the track level of the machine, so that a pallet for a flat tile, for example, need not be excessively deep and can be reduced to a size necessary to withstand the extrusion pressures only.
- a height adjustable track level can be obtained.
- height adjustment of a track along which the pallets are to be conveyed may be effected mechanically, hydraulically or pneumatically.
- the machine includes a fixed first track to provide a relatively low track level, and a second track removably arranged above said first track to provide a higher track level.
- the arrangement may be such that the first track, being secured in position, provides lateral and longitudinal support to the second track.
- suitable bridging means may be provided to span the first track and support the second track, and such bridging means may itself be of adjustable height so as to provide a variable level of the second track.
- the support means for pallets will generally include a plurality of laterally spaced, longitudinally extending tracks each corresponding to a particular lateral reference point on the pallets to be conveyed.
- the machine includes three or more laterally spaced tracks for supporting the pallets, the two outer tracks being at a fixed level and the or each inner track being arranged to provide a track level of adjustable height.
- four laterally spaced tracks are provided.
- FIG. 1 is a plan view of pallet support means of a tile making machine
- FIG. 2 is an end view of the support means in the direction of arrow "2" in FIG. 1;
- FIG. 3 is an enlarged cross-sectional view on 3--3 of FIG. 1.
- the support means 1 for the pallets comprises four tracks 2, 3, 4, 5 extending longitudinally from a pallet propulsion unit 6 through a tile extrusion device (not shown) of the machine.
- Each of these tracks is provided with a wear-resistant strip 7, as seen in FIG. 3 which shows tracks 2 and 3.
- Two channel sections 8 and 9 are rigidly secured to the machine and extend longitudinally thereof to provide support for the tracks.
- the outer tracks 2 and 5 are disposed above the channel sections and are bolted thereto (see FIG. 3).
- a hortizontal plate member 10 is welded to the channel sections and carries the inner tracks 3 and 4.
- FIG. 3 shows how a height adjustable track level is provided by the support means 1 in this embodiment.
- a track 11 is conventionally bolted directly to the plate member 10 and extends longitudinally. This track 11 can provide a relatively low track level 12 when tiles of deep profile are to be formed, requiring deep pallets.
- means are provided which bridge the track 11 so that another track i.e. track 3 can be secured thereabove, so as to provide a higher track level 13 for pallets used in forming tiles of a flatter profile.
- the bridge means comprises a pair of legs 14 and 15 disposed one on each side of the track 11 and a cross-member 16 bolted to these legs by bolts 17 and 18.
- the bridge means may itself provide height adjustment if desired.
- Countersunk bolts 19 secure the track 3 to the cross-member 16.
- Lateral guide means 20 are provided on one side of the support means 1, comprising a guide support plate 21 to which is bolted a lateral guide member 22 for the pallets.
- a shim 23 intervenes between the support plate 21 and the guide member 22.
- the support means 1 can provide a track level which is adjustable in height simply by placing one track on top of another.
- a variable track level can be provided in other ways such as by height adjustment of a single track, e.g. mechanically by using threaded track support members which may be turned to give the required up or down movement.
- Such an arrangement may be electrically or manually operated.
- Another possibility would be to use removable spacer elements or alternatively, hydraulic or pneumatic height adjustment could be effected.
